Afterburner chamber behind a combustion furnace of a combustion installation for chemical waste

Abstract: The invention relates to an afterburner chamber behind a combustion furnace of a combustion installation for chemical waste, etc., with burners arranged in the side walls of the chamber and directed into the inside of the chamber for injecting liquid, pasty or gaseous waste through a nozzle. It is characterised in that the burners (10) are concentrated essentially in the lower half of the chamber (2) adjacent to the discharge of the gases from the combustion furnace (6) into the chamber (1) and the slag discharge (9) and are directed downward at an angle of inclination of 30 - 60@ to the longitudinal axis (L) of the chamber.

Refuse incinerator with vertical combustion chambers - has larger afterburner chamber connected to main chamber below it of different shape.

Abstract: The main combustion chamber (4) has a bottom grate (8) for ash discharge, a loading mechanism (6) for solid refuse (14), a burner (18), and an air supply system (20). The afterburner chamber (3) is coaxial to the main one,with its own burner (19), air supply (21), and a discharge fluid (25). The chambers are separate and of different shapes, connected via an opening (23) narrower than both. The afterburner chamber is of larger vol. than the main one and is situated above it. There can be a third vertical expansion chamber (2) above, coaxial to the afterburner chamber, and with an air and/or water supply system (22) at the bottom, so as to cool the exhaust gas. USE/ADVANTAGE - For solid a liq.refuse,with simple and reliable feed and reduced danger of clogging.

Effect of water vapor on combustion of magnesium hydrocarbon slurry fuels in small-scale afterburner

Abstract: Report presenting testing of JP-3 fuel and a slurry of 60 percent powdered magnesium in JP-3 fuel in a small-scale afterburner in the presence of large quantities of water vapor. The results indicated that total temperature, combustion efficiency, and air specific impulse were improved when the magnesium slurry was used, but the improvements came at the cost of increased liquid consumption.

Catalytic exhaust gas afterburner - wit heater on smaller unit near engine actuated by ignition switch and thermocouple

Abstract: A catalytic after combustion system for the exhaust gases of motor cars is divided into a small catalytic unit close to the engine, and a larger one at a suitable remote spot. The small unit is fitted with an electric heater which is cut in by the ignition switch and cuts out when a certain temp. has been reached. This produces purified exhaust gases from the start. A temporary stop of the car engine still keeps the small catalytic unit at a high temp., thus improving its efficiency.

Closed Brayton cycle direct contact reactor/storage tank with O2 afterburner

Abstract: A closed cycle Brayton direct contact reactor/storage tank uses an afterburner to assist in removing metal vapors from the working fluid. The direct contact reactor/storage tank operates by bubbling an inert gas through liquid metal fuel. The inert gas picks up metal vapors from the fuel. The afterburner comprises a predetermined amount of oxygen, O 2 , being fed to a filter cavity within the reactor/storage tank and having the metal vapors react directly with the O 2 forming a solid oxide that remains and does not circulate as part of the working fluid throughout the external parts of the Brayton cycle outside of the reactor/storage tank causing damage to system components.
